APPENDIX 4: Transformer Upgrade
Should you need to change a transformer to any Mealstream 501 product, you should use the
new 30Z1233 ( 50Hz power supply ) or 30Z1230 ( 60Hz power supply) multi-tap transformer, see
matrix below.
Should you have an oven where just one transformer has failed, you can mix an old transformer
with a new transformer on the oven.
Note: The capacitor values remain the same when using the new 30Z1233 or 30Z1230 transformer.
